The England international scored his sixth goal for the club since signing from the Blues in January shortly after replacing Philippe Coutinho, before setting up Luis Suarez for a last gasp equaliser with a peach of a cross.
Sturrdige fell out of favour at Chelsea, under both Roberto Di Matteo and Rafa Benitez, and says it was important to him to show he has the ability to score against his former teammates.
“It was strange playing against them because I only left three months ago so I kind of knew their weaknesses and what their team was all about.
“I was itching to get on and the team performed well in the second half. We started attacking a lot more; in the first half we were a little bit defensive.
“The game opened up and we showed what we’re all about – it was good.”
